Manual focus only... I don't know if I'm the outlier in wishing for a Zeiss 100mm f/2 Makro. For a Sony E-mount could be fairly compact (even if FF compatible?) and lightweight (no motor). Put some delicious coatings on the front element. Presto! Good point in this thread about focus peaking, should be a charmer. Seems a perfect candidate for a manual focus lens IMO. And this lens can be splendid for both macro (errr, excuse me maKro) and portraits.

I could use my 85mm 1.4 on e-mount and still get EXIF....I forget about iris though...that may work too.

If they do 85mm first it'll be even longer for a 100 mak I bet, I'd do metabones from Canon in the mean time. Zeiss's are easy resells....don't lose too much in the event they do release an emount 100mm.
